Rough set theory [3, 4] is a theory of data analysis proposed by a polish mathematician Z.
Its main thought is to educe problems decision or sorting rules by knowledge reduction at the premise of keeping sorting capability.
The eigenvalues we get through the information collection, data processing in the experiments have are continuous values.
But the rough set theory can only deal with discrete data, so the first thing to do is discretization of data processing.

The quantitative data of the decrease in the concentration of textile dye solution were measured by using UV-Vis spectrometer and simple spectrometer which was developed recently.
From the measurement of the unirradiated solution (in the dark environment) and membrane without TiO2, it appears that there was a reduction in the concentration of the textile dye solution, but not too much compared to the irradiated fiber membrane TiO2/styrofoam.
Based on the percentage of reduction in concentration that can be calculated from the above data, the percentage of the decrease in the concentration of the solution for 30 hours can be obtained as Table 1 follows.
The decrease in absorbance of the photocatalyst test solution for 30 hours was obtained, this change has proved that there has been a reduction in the concentration of textile dye due to photocatalysis processes that occur in titania.

It is clear from the data presented in Table 1 that the Cu-coated membranes display an opposite phenomenon compared with those only coated by Pt.
Although the variations in resistance per unit length is large, and fluctuates severely upon switching the polarity for 100 cycles, it is also clear from the data presented in Table 1 that the final resistance values of the electrodes are lower than the initial values prior to cycling.
In fact, the data in Table 1 suggests that the electrode conductivity is continuously improving upon cycling.
Although the resistance data for the Cu-coated IPMC-s look promising, we observed unwanted side-reactions during our measurements.
SEM data shows that the actuator contains a lot of holes in polymer matrix.

Their activities in pH reduction and sulfate production indicating high H2S removal efficiency from the drainage collected from wastewater plant nearby the isolated area of Mae Moh, Lampang province.
The pH reduction of the broth were detected by thiosulphate agar medium and the pure isolates were thus restreaked on TS medium agar plates.
Among them, 12 isolates could be obtained after changing the color of the media from purple to colorless by their pH reduction ability on the bromophenol blue containing sulphur oxidising broth and agar medium.
The pH reduction after incubation at 25-30oC for 15 days, high acidity production together with sulfate solution accumulation to the solution (shown in Fig. 3) demonstrated high bacterial activity in H2S removal.
Conclusions These data suggest that Thiobacillus sp.

The reduction of welding-related health hazards requires interventions affecting amounts and chemical compositions of noxious substances.
The use of gas mixtures of various and improved chemical compositions leads to the significant reduction of fume and gas emissions during welding processes [2,6].
While analysing the data concerning the welding fume emission rate during welding of high-alloy steels, at the same time it is necessary to emphasize the fact that emission is also affected by shielding gas composition and by welding current.

The establishment process of the numerical model is listed as follows[4,5] : (1) Modeling: According to drilling data, field investigation and surveying data, we are to establish a three-dimensional geological model for the slope.
As the basic principle of strength reduction is similar to the progressive destruction process of slope, the deformation process of slope can be generalized as: the deformation speed is high at the very beginning, then slows down, and eventually tends to be stable. 3.2.3 Slope Shearing Stress and Shearing Strain Increment Analysis Fig. 13 The shearing stress distribution under waterlogged state Fig. 14 The shearing stress increment under waterlogged state Shown by the shearing stress distribution in Fig. 13, under waterlogged state, the shearing stress belt still concentrates around the primary slide zone, which is basically identical with shearing strain increment concentration zone (Fig. 14).

Figure 1 Region of interest (first: before compression, last: after compression of 28% reduction, middle: intermediate steps of ~5% difference in reduction).
The crystal orientation data described by Euler angles are further converted to quaternion representation and the in-plane rotation representation was achieved by projecting it along z-axis for a better comparison with the rotation result calculated by DIC [4, 5]. 5% 15% 28% Figure 2 Compressive strain maps (above) and rotation maps (below) around particle at different stages of compression.
Figure 3 (Left) EBSD misorientation map in the same region in Figure 2 with ε=0.33 (Red, Green and Blue colours are corresponded with the Euler angles between a reference pixel and the other pixels) and trace of {111} plane and (right) in-plane rotation calculated from EBSD data particle shape is outlined in green.
When the deformation goes up to 15% and 28% reduction, the strain in slip bands are up to almost 50% and 80%, with only ~10% in the between.
These agree with the EBSD data shown in Figure 3.

For the measurement of hydroperoxyl/superoxide anion radical concentration, the well known method based on ferri-cytochrome c reduction was used [11].
These data were collected at a power density of 1 W/cm2, with and without the single band filter in front of PMT.
For calibration purposes, ferro-cytochrome c was produced from the reduction of ferri-cytochrome c by sodium dithionite.
From these data, an average generation rate of 1.60 µM/min was calculated at ~ 27 °C.

Therefore, YSZ minimizes the electronic conduction of GDC as well as protects the reduction of Ceria ions [3].
All data shows clear peak of yttrium and zirconium.
Comparison with other experimental data based on Ceria based electrolyte cell, our experimental results has enough potential[7].
We can conclude potential of this experiment from OCV data achieved by YSZ/GDC bi-layered cell.
YSZ thin layer seems to perform well to block reduction and electron conductivity of ceria.

Results and discussion As evidenced by the AFM images in Fig. 1, the thickness from the height profile is around 1.0 nm, which is consistent with the data reported in the literature[10], indicating the formation of the single layered graphene oxide (GO) sheets.
Then the reduction of GO is not only concerned with removing the insulting oxygen-containing groups and other atomic-scale lattice defects, but is also aimed at recovering the long-range conjugated network of the graphitic lattice.
After the reduction with L-ascorbic acid, the intensities of all C1s peaks of the carbons bound to oxygen, especially the peaks of C=O and C-O bonds decreased rapidly, revealing that most of the oxygen containing functional groups were removed after the reduction.
